In section 3, an algorithm performing so called generalized good translation of formal languages is given in the form of an ALGOL 60 procedure. Its description is given in section 2. It is possible to translate from a formal (context-free) language into other one with help of this algorithm if certain conditions hold for both grammars. At the same time, some parts of output text may correspond ...

Chaperonins are essential for the folding of proteins in bacteria, mitochondria, and chloroplasts. We have functionally characterized the yeast mitochondrial chaperonins hsp60 and hsp10. In the presence of ADP, one molecule of hsp10 binds to hsp60 with an apparent Kd of 0.9 nM and a second molecule of hsp10 binds with a Kd of 24 nM. In the presence of ATP, the purified yeast chaperonins mediate...

Mortalin/mtHsp70 (mitochondrial Hsp70) and HSP60 (heat-shock protein 60) are heat-shock proteins that reside in multiple subcellular compartments, with mitochondria being the predominant one. In the present study, we demonstrate that the two proteins interact both in vivo and in vitro, and that the N-terminal region of mortalin is involved in these interactions. Suppression of HSP60 expression ...

The Ocean Drilling Program (ODP) has amassed large databases (including paleontological) as a result of its research on the geology of the ocean floor. ODP has begun to present its research results in electronic proceedings that will soon completely displace paper publications. Palaeontologia Electronica (PE) has pioneered the concept of an all-electronic paleontological journal with no paper e...

In the routine use of typical media for the microbiological determination of the sixteen amino acids standard curves have accumulated which reveal the amounts of each amino acid required for the growth of the assay organism when all other amino acids are present in excess. Thus it was observed that the relative amounts of the various amino acids needed by Leuconostoc mesenteroides P-60 did not ...

This report contains details of over 100 Algol 60 test programs available from NPL which can be used to validate a compiler. Interpreting the results of the tests requires a good knowledge of Algol 60.

The interaction of the chaperonin GroEL14 with its cochaperonin GroES7 is dynamic, involving stable, asymmetric 1:1 complexes (GroES7.GroEL7-GroEL7) and transient, metastable symmetric 2:1 complexes [GroES7.GroEL7-GroEL7.GroES7]. The transient formation of a 2:1 complex permits exchange of free GroES7 for GroES7 bound in the stable 1:1 complex. Electrophoresis in the presence of ADP was used to...
